OP=11.2
m<Q= 42⁰
m<R=48⁰
The tools used are....
I have used the property of Pythagoras Theorm to get the length of side QP, I have also used the property of inverse function of sin to get the measure of angle Q and the property of sum of angles of triangle to get measure of angle of R
Answer:
Domain -5 ≤x<1
Range -4 ≤y<7
Step-by-step explanation:
The domain is the values that x takes
X goes from -5 included to 1 not included
-5 ≤x<1
The range is the values that y takes
y goes from -4 included to 7 not included
-4 ≤y<7
